To all whom it may concern'.

Be it known that I, DAVID L. MEKEEL, residing at Sewickley', in the ,county of Allegheny and State ofl Pennsylvania, a citizen of the United States, have' invented or discovereda certain new and useful Improvement in Ingot-Manipulators, of which improvement the following is a specification.

described and claimed.

The invention described herein relates to certain ,improvements in mechanism for turning lingots, slabs, etc., on their axis during therolling operation, and for retaining such pieces, when necessary,` in the position t which .theyNhave been turned.

The invention is .hereinafter more fully -In the accompanymg drawings forming a part of this'specification Figure 1 is a top plan view. showing the portion of the feed table of the `rolling mill having my improved manipulator applied thereto; Fig. 2 is a view partly in sectlon and partly in elevation of the mechanism shown in Fig. 1; Fig. 3 is a sectional view lon an enlarged scale, vthe 'plane of section being indicated by the line IIL-III Fig.l 1, and the motor being omitted; Fig. 4 is a view similar to Fig. 3, showing the parts of the manipulator in vturning an ingot;

Fig. 5 -is an elevation looking at the outer side of one of the mani ulator elements Fig. i

is a view similar to I* 1g. 4 illustrating a modin lication of my improvement and F1g.g7' 1s a sectional elevation on a plane indicated by In the practice of my invention the rolling mill table is of the usual and any suitable construction, and provided with feed rollers 2 preferably positively driven to feed the ingot to the rolls (not shown) and side or guide plates 2a. Rails 3 extend transversely of the table between'rollers, their ends being supported in the side frames of the table. These rails support heads or abutments 4 and 5 vadapted to slide along the rails transversely of the table; in turningor shifting an ingot, slab, etc. ments as 4, which for convenience I W1ll term the holding abutment, is connected to a suitable motor, whereby .it may berec1pro cated, suchfor example as the fluid pressure cylinder 6. The other head or abutment 5 is connected to a Huid pressure cylinder 7 on `the opposite side of the feed table. These heads or abutments are withdrawn into gaps or openings in theside ra1ls'eXce t when operating on the-article lbelng ro led. As 1s One of these heads or abutthe usual practice, the valves controlling Patented sept: 29, 1908.

the llow of fluid pressure to and from these4 i cylindersare located at a convenient point lwhere each can be operated in turn or simultaneously as required by the work to be performed.

A rock shaft 8 is mounted on the head 5and lhas keyed thereto turning arms 9 which may operate either directly or through slides 10 to turn the ingot, slab, or other article. 'Ihe .slides when employed are arranged in guide grooves .formed in the inner face of1 the head as shown in Figs. 1 to 5, and are provided Y with lugs or projections 11 extending beyond the face of the head or abutment. The `slides are provided with slots oro enings for the reception of the ends of t 1e turning arms S. l,

The rock shaft is o eratively connected to a suitable motor as t e fluid pressure cylinder 12, in any suitable manner. The connection shown consists of an arm 13 on the rock shaft connected by `alink 14:l to a slide 15 supported on 'guides 16 on the head or abutment 5 and connected to the piston rod 1.7 of the cylinder 12. The bearings for' the rock shaft S have removable ca s l18,.so that by removing such caps and isconnecting the arm 13y from the slide the shaft and arms 9 can be easily withdrawn and the slide 10 removed, and new arts inserted. The lugs'y or projections 11 o theslides areso located.

that when the latter are in their lower orin'- operative position the lugs or'projections will be below the line of movement'of an ingot or slab resting upon the rollers.

When it is desired to run an ingot or slab, the head or abutment 5 is moved in towards the ingot or slab until the lugs 11 are under' one edge of such ingot or slab. The slide is then raised the lugs llengaging the ingot or slab near one edge and turning the slab as indicated in Fig. 4. In order to prevent the ingot or slab sliding off of the lugs or projections, the holding head or abutment is moved up against the ingot or in such relation thereto as to prevent the lateral sliding of the'i'ngot, but not to interfere with the turning movement. .In order tol insure the lugs following up and maintaining contact with the ingot or slab in turning, the head or abutment is gradually moved inwards as the 'turning' progresses, or the same urpose may be attained by moving in the ho ding head or abutment 4. It will be observed that the lugs 1l extend down vertically vfrom the 'porting fui'icjj'irin may hinter e .,ingot.
